In true Cersei Lannister form, the actress bats down every insult Jimmy Kimmel throws at her

How do you talk to each other, Game of Thrones style? You spew choice insults and comebacks that shame the best of improv actors, goblet of wine in hand, of course. Do that with Jimmy Kimmel, and you score extra points for being on par with Lena Headey herself.

The actress, who plays the ambitious Cersei Lannister in the HBO series based on George R. R. Martin's A Song of Ice and Fire novels, sat down with Jimmy Kimmel on Tuesday night and began playing insult ping pong. It was all planned, of course, so no hard feelings. But what a party it would've been if Peter Dinklage (Tyrion Lannister) was invited too, don't you think?
